The invention concerns a method of transmitting data from a plurality of sources (22i) to a plurality of receivers (24) via a single gateway (21) using at least two separate data transmission media (23i), said receivers (24) being able to receive selectively data transmitted on any of said transmiss
The invention concerns a method of transmitting data from a plurality of sources (22i) to a plurality of receivers (24) via a single gateway (21) using at least two separate data transmission media (23i), said receivers (24) being able to receive selectively data transmitted on any of said transmission media (23i), the method being characterized in that it assures dynamic distribution of said data to be transmitted to said transmission media (23i) in accordance with a global analysis of all of said data to be transmitted, signalling data (32; 42) regularly specifying to each of said receivers (24) the transmission medium or media (23i) it is to use.

The invention concerns a method of transmitting data from a plurality of sources (22i) to a plurality of receivers (24) via a single gateway (21) using at least two separate data transmission media (23i), said receivers (24) being able to receive selectively data transmitted on any of said transmission media (23i), the method being characterized in that it assures dynamic distribution of said data to be transmitted to said transmission media (23i) in accordance with a global analysis of all of said data to be transmitted, signalling data (32; 42) regularly specifying to each of said receivers (24) the transmission medium or media (23i) it is to use. 1. A System (1; 49; 65) comprising a data source (2, 4; 50; 66) for supplying an information packet stream, and a processing device (3; 51; 69) for processing an information packet stream, and a data sink (4, 5, 6; 52, 53; 67) for receiving an information packet stream, the data source (2, 4; 50; 66) comprising source means (11, 44) for supplying to the processing device (3; 51; 69) an information packet stream including information packets, which information packets contain digital data coded in accordance with a first coding method and in accordance with a second coding method and representing picture information or sound information or data information, and the system (1; 49; 65) including decoding means (48) adapted to decode digital data contained on the information packets and coded in accordance with the first coding method, characterized in that the system (1; 49; 65) comprises insertion means (37; 62; 71) which--when digital data coded in accordance with a second coding method are present in the information packets--are adapted to insert further digital data coded in accordance with the first coding method into further information packets of the information packet stream, the coded further digital data containing picture information or sound information as additional information relating to the digital data contained in the information packets, which digital data are coded in accordance with the second coding method and can therefore not be decoded correctly by the decoding means (48). 2. A system (1; 49; 65) as claimed in claim 1, characterized in that the source means (2, 4; 50; 66) are adapted to supply an MPEG transport stream comprising MPEG transport stream packets as an information packet stream in accordance with an MPEG standard (ISO/IEC 11172-1, ISO/IEC 13.818-1) to the processing device (3; 51: 69), which MPEG transport stream packets contain digital data, which represent picture information or sound information or data information, coded in accordance with an MPEG coding method in compliance with an MPEG standard (ISO/IEC 11172-2, ISO/IEC 11172-3, ISO/IEC 13.818-2 or ISO/IEC 13.818-3) and in accordance with a second coding method, and the system (1; 49; 65) comprises decoding means (48) adapted to decode digital data contained in the MPEG transport stream packets and coded in accordance with and MPEG coding method, and the insertion means (37; 62; 71), when digital data coded in accordance with a second coding method and contained in the MPEG transport stream packets are present, are adapted to insert further digital data coded in accordance with an MPEG method into further MPEG transport stream packets of the MPEG transport stream. 3. A data source (2, 4; 50; 66) for supplying an information packet stream, comprising source means (11, 44) for supplying an information packet stream including information packets, which information packets contain digital data coded in accordance with a first coding method and in accordance with a second coding method and representing picture information or sound information or data information, characterized in that insertion means (37; 62; 71) have been provided, which insertion means--when digital data coded in accordance with a second coding method are present in the information packets--are adapted to insert further digital data coded in accordance with the first coding method into further information packets of the information packet stream, the coded further digital data containing picture information or sound information as additional information relating to the digital data contained in the information packets. 4. A data source (2; 50; 66) as claimed in claim 3, characterized in that the source means (11) comprise first coding means (13) for coding digital data in accordance with a first coding method and for supplying coded digital data, and the source means (11) comprise second coding means (14) for coding digital data in accordance with a sec
